Preheat your oven to 400°F. Peel the golden beets and dice them into uniform 1-inch cubes.
On a parchment-lined baking sheet, toss the beets with 0.5 tbsp of olive oil, 0.125 tsp of sea salt, and 0.125 tsp of black pepper.
Roast the beets for 25-30 minutes, or until they are fork-tender and slightly caramelized.
While the beets roast, whisk together the orange juice, orange zest, honey, and balsamic vinegar in a small bowl to create the glaze.
Season the chicken breast with the remaining sea salt and black pepper.
Heat the remaining 0.5 tbsp of olive oil in a medium skillet over medium-high heat. Sear the chicken for 6-7 minutes per side until golden brown and the internal temperature reaches 165°F.
During the final 2 minutes of the beets' roasting time, pour the orange glaze over them and toss well to coat, returning them to the oven briefly to thicken the glaze.
Slice the chicken and serve it alongside the glazed golden beets over a fresh bed of baby arugula.
